What are toe rands and when do I need to replace them?
The toe rand is the rubber that covers the toe of the shoe and wraps under the sole. You will need to replace the rand if there is a hole, tear, or weakness at or above the seam where the sole meets the rand. To assess: press on the rand and feel for weaknesses in the rubber. Generally, if one shoe has an obvious hole, the other shoe probably has a weakness also.
